Sigma link presents modular tooling systems that are perfectly balanced for maximum rigidity due to high pre-loading forces and large contact surfaces. These tooling systems feature maximum torque transmission for clock or counter-clock wise rotation without loss of interchangeability. They have minimal run out due to concentric clamping and have guaranteed cutting edge orientation, regardless of the number of components assembled. Vibration damping is due to friction created between the mating components and repeatable seating precision is with a maximum radial error of 0.002 mm. The product range includes: micro boring heads, carbide boring bars, tappig holders, coolant adapters and other modular tools and clamping systems.
